12. Justified

Why we're excited: It feels like forever since we last rocked with Deputy Raylan Givens (Olyphant), the cowboyish, sly-tongued U.S. Marshal with a gun hand as fast as lightning and a mountain worth of daddy issues. The superb backwater Kentucky-set series features an original universe unlike any other setting in TV's current crop, populated with a rich cast of characters that spout the best, wittiest dialog on the tube.

Details on season four's main arc are scarce, but we do know that while Raylan and estranged wife Winona are expecting, the series will continue to focus on its core relationship: that of Raylan and former best friend turned criminal mastermind Boyd Crowder (Goggins). Three seasons in, Justified has earned a reputation for crafting fantastic antagonists for Raylan to butt heads with, and we're expecting the latest batch of episodes to continue to deliver on that regard. This is hands-down the best show you're not watching (cheers to all who are already tuning in), so add it to your New Year's resolutions and get familiar.
